The proposal for the UV completion of gravity is the quantum field theory as defined by the general quadratic gravity action. Due to renormalization effects, \(m_G/m_{\rm Pl}\)  becomes an asymptotically-free running coupling. The QFT is stable and unitary and it is only in this context that the massive ghost state can be properly treated and understood [1]}, [2]}, [3]}. A picture for ultra-Planckian scattering then emerges [4]}. But our interest here is with the macroscopically large states of this gravity theory, and for this we turn to the static solutions of the classical field equations from (). There would normally be the question of why a classical theory is being considered with two and four derivatives and not higher derivatives. This receives some explanation in the context of the renormalizable and asymptotically-free QFT that is defined by the \(2+4\)  derivative action. In particular the high curvatures inside the 2-2-hole are probing the asymptotically free region of the QFT.
